Here in WA state, the minimum wage per hour is $15.74 (higher in some areas). Tipping culture says 20%, but that’s generally to support lower paid waitstaff in areas that can pay less than minimum wage by employers. Where/What are you tipping and what kind of service would you expect for a 20% tip?
I tip for 2 things: restaurants and food delivery.
For food delivery, I tip $24.
For restaurants, I tip around the same unless it is a particularly fancy place with a tasting menu that means they’re servicing the table way more often than a normal restaurant.
